Motoichi Ohtsu received the B.E., M. E., and Dr. E. degrees in electronics engineering from the Tokyo Institute of Technology, Tokyo, Japan, in 1973, 1975, and 1978, respectively.
In 1978, he was appointed a Research Associate, and in 1982, he became an Associate professor at the Tokyo Institute of Technology. From 1986 to 1987, while on leave from the Tokyo Institute of Technology, he joined the Crawford Hill Laboratory, AT&T Bell Laboratories, Holmdel, NJ. In 1991, he became a Professor at the Tokyo Institute of Technology. Since 1993, he has been concurrently the Leader of the "Photon Control" project of the Kanagawa Academy of Science and Technology, Kanagawa, Japan. Since 1998, he has been concurrently the Leader of the "Localized Photon" project of ERATO(Exploratory Research for Advanced Technology), JST(Japan Science and Technology Corporation), Japan.
He has written over 320 papers and received 87 patents. He is the author and co-author of 39 books, including seven in English, entitled Highly Coherent Semiconductor Lasers (Artech House, Boston, 1991), Coherent Quantum Optics and Technology (Kluwer, Dordrecht, 1993), Frequency Control of Semiconductor Lasers (Wiley Interscience, New York, 1996), Near-Field Nano/Atom Optics and Technology ( Springer Verlag, Berlin, 1998), Near-Field Nano-Optics (Kluwer Academic/Plenum Publishers, New York, 1999), Optical and Electronic Properties of Nano-matters(Kluwer Academic/KTK Scientific Publishers, Dordrecht/Tokyo, 2001), and Progress in Nano Electro-Optics ( Springer Verlag, Berlin, 2002).
In 1999, he was the Vice-President of the IEEE/LEOS Japan Chapter, and in 2000, he was appointed as the President. From 2000, he is an executive director of the Japan Society of Applied Physics. He served as a Technical Program Co-chair for the 4th Pacific Rim Conference on Lasers and Electro-Optics(CLEO/PR01), 2001. He has been a tutorial lecturer of the SPIE and the OSA. His main fields of interests are the nano-photonics and atom-photonics.
He is a senior member of the Institute of Electrical and Electronics Engineers, a member of the Japan Society of Applied Physics, the Institute of Electronics, Information and Communication Engineering of Japan, the Institute of Electrical Engineering of Japan, the Optical Society of America, and American Physical Society. He has been awarded ten prizes from academic institutions, including the Issac Koga Gold Medal of URSI(International Union of Radio Science) in 1984, the Japan IBM Science Award in 1988, two awards from the Japan Society of Applied Physics in 1982 and 1990, and the Inoue Science Foundation Award in 1999.
